This is kind of a sensitive and even a little painful subject for me, so please forgive me if my post seems confused or awkwardly phrased :-).
I have a friend with whom I've been close for over a decade, but for the last five years or so (maybe longer?) I've become ever more reluctant to get together with her because every. single. time. I see her, she ends up commenting negatively on my footwear. In the grand scheme of things, I know this is not a big issue; but it's caused enough hurt feelings on my part that it really does run the risk of damaging our friendship (if it hasn't already).
As examples, the kinds of things she usually comments on unfavorably are:
-- how much I paid, or how much it looks like I paid, for a pair of shoes (to which I've responded by hedging or just pleading the 5th)
-- negative comments about heel height (they can't be good for my feet, she's surprised I haven't broken an ankle yet, etc.)
-- comments about the supposed lack of comfort
It's gotten to the point where I've started adjusting my shoe choices in order to avoid the negative commentary (for instance I'll wear flats, flip-flops, etc, instead, although this sometimes also elicits negative feedback in the form of, "oh, you're wearing sensible shoes for once!").
So now that I'm done whining ;-), the real purpose of my post is to request advice for a polite way to address this. I love my friend, and this is one of the few points of disharmony in our relationship, so I want to somehow tactfully, sensitively let her know that I don't appreciate these comments... and I'd also like to ask her to avoid making them in the future. Unfortunately, I've absolutely no idea how to go about doing it
